There is an old native American legend that describes the existence of thirteen ancient crystal skulls, the size of human skulls, that are said to speak or sing. The legend says that these skulls hold important information about the origins, purpose and destiny of mankind, and the answers to some of the great mysteries of the universe. According to the legend, one day all thirteen crystal skulls will be rediscovered and brought together to reveal this information, but the human race must first be sufficiently developed so as not to abuse this knowledge.

When the authors first heard this legend deep in the jungles of Central America they thought it merely a colourful story, until they discovered that, earlier this century, a real crystal skull has been found in some ancient Mayan ruins. Several other crystal skulls have since come to light. All are of mysterious origin and all are surrounded by tales of magic and incredible psychic or healing powers.

Unable to get any clear explanations for these phenomena, the authors set out on their own quest to find the truth about the skulls. They encounter psychics, UFO hunters, shamans, mystics and medicine men on a journey of discovery that takes them from the British Museum in London to the deserts of the United States, from the science labs of Hewlett Packard to the cold snows of Canada and the tropical jungles of Mexico, Guatemala and Belize. At sacred gatherings of native elders they learn of ancient wisdom kept secret for hundreds, if not thousands, of years. They hear of startling prophecies concerning events that will happen on this Earth in the immediate future, prophecies that question the very survival of the human species on this small island we call home. This is the story of their remarkable discoveries.

The crystal skulls are a mystery as profound as the Pyramids of Egypt, the Nazca Lines of Peru, or Stonehenge. Many indigenous people speak of their remarkable magical and healing properties, but nobody really knows where they came from or what they were used for. Were they left behind after the destruction of a previous world, such as Atlantis? Are they simply ingenious modern fakes or can they really enable us to see deeply into the past and predict the future? Searching for the answers takes the authors on a fantastic odyssey through both the physical and the spiritual world.
